[Abstract]:Wind power has become the fastest and most competitive power generation technology by virtue of its mature technology, low cost and advantage of large-scale development and utilization. With the continuous improvement of wind power permeability in power grid, the role of wind turbine relative to conventional units has changed from "certain supplement" to "partial substitution", which has brought a lot of influence to the safe and stable operation of the system. Due to the relatively smooth and stable wind power output of the large-scale wind power cluster, the wind field group is unified to accept the real-time control of the dispatching center. However, the wind turbine unit is usually in the maximum generation operation mode, which is lack of support to the frequency of the power system. When the load fluctuation in the system is very large and the regulating capacity of AGCs is insufficient and the frequency index is deteriorating, how to make the wind field group release the fast regulating capacity to supplement the regulating capacity of the deficient AGC units. Maintaining system frequency stability has become an urgent problem after large-scale wind power grid. In order to ensure sufficient peak-shaving and frequency modulation capacity in the system, this paper mainly focuses on the autonomous power allocation among wind farm groups under certain circumstances and the strategy of coordinating conventional units to participate in the frequency regulation of the system. Firstly, according to the operation data and output power curve of a practical wind farm, the power output characteristics of wind farm are analyzed. Based on the regulation characteristics of wind turbine and the principle of the first and second frequency regulation of the system, the influence of wind power grid connection on the frequency regulation of the system is analyzed. Then, a series of grid guidelines and regulations issued by some countries with high wind power permeability to deal with the powerlessness of wind turbine against frequency change are introduced. Secondly, the characteristics of wind field and wind field are analyzed qualitatively and qualitatively by using the relative indexes of this paper. The wind field is divided into three categories according to the wind power forecast trend by using the ultra-short-term power prediction information of wind power. The control principle of all kinds of wind field groups is defined, and the specific power distribution method is given. The ultrashort power prediction information of a wind power base is used to verify its effectiveness, which lays a foundation for the subsequent cluster wind field groups to participate in the frequency control strategy of the system. Finally, in the analysis of non- units, On the basis of the coordination relationship between the active power regulation of wind field group, this paper puts forward the control strategy that the wind field group releases part of the regulating capacity to supplement the deficient AGC unit's regulating capacity to participate in the frequency regulation of the system, and gives the non-AGC unit. The coordination conditions between the wind field group and the AGC unit are adjusted, and the coordination scheduling model of the three sets of units is established. An example is given to illustrate the rationality and applicability of the proposed coordinated control strategy and the mathematical model established in this paper.
